Understanding the Lab Diamond Color Grade and the IGI Scale
Diamonds, whether natural or lab-grown, come in various shapes, sizes, and colors. Traditional white diamonds (actually clear) are especially popular and graded based on color, typically on a scale ranging from D to Z. These sparkling gems are commonly found in necklaces, earrings, and especially engagement rings.
The International Gemological Institute (IGI), established in 1975, now has global headquarters. IGI independently verifies lab diamonds, grading them on factors such as cut, clarity, color, and carat.
IGI certifies diamonds using a graded color scale. Diamonds with less color receive better grades, translating to more sparkle. The color grading ranges from D (colorless) to Z (noticeably yellow or brown). Let’s delve into the lab-created diamond color chart to understand more about these grades:
Color Grades from D to Z:
Grade D
This is the highest available color grade. A ‘D’ grade color lab diamond is completely colorless and shows no signs of color even under magnification.
Grade E & F
Nearly as perfect as Grade D diamonds, E & F grade diamonds appear colorless to the naked eye. While gemologists might discern the differences, average jewelry buyers typically cannot.
Grade G to J
These diamonds look relatively colorless to the naked eye, similar to E and F grades, but are not of the same high quality. They cost much less than D, E, or F grades.
Grade K to M
Diamonds in this grade exhibit a faint tint—often a pale-yellow hue. Though still beautiful and possessing a warm tone, they are not considered high quality. At Artful Bracelets, we only offer D to L colored lab diamonds to ensure maximum brilliance and longevity.
Grade N to R
Lower-grade diamonds with a very light tint. Diamonds graded N to R typically have a noticeable yellow or brown hue, making them less expensive.
Grade S to Z
Diamonds in this range have a light tint with evident brown or yellow shades and are significantly cheaper.
Does fluorescence impact diamond color?
Under UV light, blacklight, or direct sunlight, a diamond might exhibit fluorescence, which can give it a slightly cloudy appearance.
Does the color grade affect the price?
Color is one of several factors influencing diamond pricing, alongside shape, size, clarity, and carat. Higher-grade diamonds cost more, with D being the best. E and F are also excellent choices.
While diamonds graded G to J are still beautiful and more affordable, they may have minute yellow hues that might not be noticeable without magnification. If precision matters to you, opting for a higher grade could be worthwhile. Need assistance?

What About Accent Diamonds–What Color Should I Pick?
Accent diamonds are smaller stones set around the main diamond to enhance its appearance. To complement the center stone, choose accent diamonds that harmonize in shape, size, and color. Generally, accent diamonds one to three shades lower than the main stone are ideal. A reputable jeweler will expertly match accent diamonds to your center stone.
Fancy Lab Created Diamond Colors
If you’re interested in diamonds with a touch of color, various shades are available. Lab-grown diamonds offer diverse hues, from pale to vivid yellows (resulting from controlled nitrogen exposure), to oranges (from solvents during the growth process), and blues (due to boron exposure). Pink diamonds are another favorite, with colors added through irradiation and annealing post-formation.
Does Lab-Grown Diamond Color Grade Matter?
When it comes to carat weight
If you want a larger diamond or bigger carat size, do not compromise on color grade. The cut and color are most significant in determining a diamond ring‘s beauty. For diamonds above 1 carat, a G or H color grade minimizes yellow tints. If unsure about carat weight, choose a color grade between G and J.
What About the Color of the Mounting?
Even if your lab diamond isn’t a D grade, once set in a ring, its color is harder to detect. The mounting color can also affect the diamond’s appearance. White metal emphasizes yellow tints, while yellow gold minimizes them, with rose gold having a similar but subtler effect.
For K-Z grade diamonds, opt for yellow or rose gold mountings to reduce visible yellow tint. Your choice of metal depends on personal preference and how it complements the diamond’s color.Your partner’s daily routine, for instance, may dictate the type of metal you choose for durability and cost efficiency. Metals come in various types, differing in properties such as durability, shine, weight, and cost, depending on your preferences.
